ABSTRACT:
A safety cartridge for thermostatic mixer taps includes a thermostat carrying a slide having two valves for shutting off respective flows of hot and cold water. A region of the thermostat is housed in a piston having a part which is guided by a reversibly releasable guide mechanism adapted to guide the piston as long as the valve for shutting off the flow of hot water is not in contact with its seat, to eliminate the guidance when the valve bears on the seat, to allow misalignment of the piston, of the thermostat and of the slide so that the valve is pressed against and sealed to the seat, and to re-establish the guidance when the valve leaves its seat.
